an y electronic equipment or system s in the fields of I CT (inform ation and communication technology) and of industrial/infrastructure control systems, is becom ing a critical issue I n general, security is achieved by restrictions and protections against im proper or unauthorized accesses from both hardware and software sides of the systems Considering the security of the hardware of electronic equipment or system s, which are built up in the mechanical structures such as cabinets based on I EC 60297 series and I EC 6091 series, it depends on conditions of their installation sites, on the security level of system hardware which provides access protection at the installation sites, and on the robustness of the mechanical structures and of their m echanical locks both at the access gates/doors of the installation sites and of the mechanical structures Therefore, a classification of the installation conditions and of the levels of security measures for hardware is very im portant for design and practices of various electronic equipm ent or system s, which are used in the field of I CT, industrial control, transportation and others From this point of view, this docum ent intends to clarify the relationship between the installation conditions and the security requirements for indoor cabinets, and to provide the required perform ances and test methods on m echanical com ponents related with security provisions for indoor cabinets which are in accordance with I EC 60297 series and I EC 6091 series Vandalism protection aspect is applied by user-specific requirem ents in general Therefore, this document has no definition of vandalism –6– I EC 61 587-6: 201 © I EC 201 M E C H AN I C AL S T RU C T U RE S F O R E L E C T RI C AL AN D E L E C T RO N I C E Q U I P
